Open the water tank cover, drive the car to feed oil, and observe whether the water in the water tank is in a vortex. As the throttle increases, the water will vortex very strongly. If the response is not great, wait until the water temperature is at a hot spot, the electronic fan starts, and the thermostat turns on. There will be a whirlpool, and the whirlpool will change as the throttle changes, so that the pump is not broken.
In the cylinder block of a car engine, there are multiple water channels for the circulation of cooling water, which are connected to the radiator (commonly known as the water tank) placed at the front of the car through water pipes to form a large water circulation system. The water outlet on the engine is installed. There is a water pump, driven by the fan belt, to pump out the hot water in the engine block waterway and pump in the cold water. There is a thermostat next to the water pump. When the car is just started (cold car), it is not turned on, so that the cooling water does not pass through the water tank, but only circulates in the engine (commonly known as small cycle), until the temperature of the engine reaches 95 degrees or more When it is turned on, the hot water in the engine is pumped into the water tank, and the cold wind when the car is moving forward blows through the water tank, taking away heat. Centrifugal water pumps are widely used in automobile engines. Its basic structure is composed of water pump casing, connecting plate or pulley, water pump shaft and bearing or shaft bearing, water pump impeller and water seal device and other parts, which are the main components of the automobile.
